The latest smartphone sales data from Kantar Worldpanel ComTech, for the three months to August 2013, shows Windows Phone has posted its highest ever sales share of 9.2% across the five major European markets* and is now within one percentage point of iOS in Germany. Android remains the top operating system across Europe with a 70.1% market share, but its dominant position is increasingly threatened as growth trails behind both Windows and iOS.

Good news for Microsoft - bad news for Apple. Of course, we'll have to see how the iPhone 5S and 5C affect these numbers.

Isn't the automotive infotainment market shifting more towards linking to the driver's smartphone?

Yes and no.

The driver's phone (or any phone that is paired via Bluetooth and in range, could be a passenger's), is regarded as the primary source of data, e.g. media files, etc.

So you get into the car, the car recognizes your phone and becomes the primary interface for the combined functionality.
Music plays through the car's speakers, music and calls are controlled through interface elements provided by the car, e.g. buttons on the steering wheel, display caller info in a dashboard mounted screen, etc.
